AUGUSTUS (I. GALE, OF ALBION, MICHIGAN, ASSIGNOR TO THE GALE MANUFACTURING COMPANY, OF SAME PLACE.

SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 325,069, dated August 25, 1885.

Application filed March 18, 1885.

To aZZ whom it may concern.-

Be it known that I, AUGUSTUS J. GALE, of Albion, in the county of Calhoun and State of Michigan, having invented new and useful Improvements in Sulky-Plows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in the construction of what are ordinarily denominated sulkyplows, or that class of plows which are supported from a frame, which in turn is sup ported through the means of axles or arms by the traction wheels. In such plows, in practice, one of the wheels when the plow is in operation runs in the furrow upon a lower plane than the opposite wheel, and this difference in the plane brings a strain upon the hub or wheel running upon the lower plane, and thereby produces a wear in the hub, which in time militates against the perfect working of the device, and in such structures the frame is usually made ofiron, and the axle arm, which is made of steel,hasashoulder formed upon it to rest against the iron frame, through which the arm is projected, and the steel shoulder has a tendency to cut the iron portion of the frame and thereby increase this lost motion. In continuous wear the lower portion of the axle gradually wears flat, or nearly so, and it becomes necessary frequently to replace such worn arms.

The object of the present invention is to so construct a sulky-plow frame and its axlearms that all wearsuch as occasions looseness of the parts or lost motionmay be at on cc taken up, all danger of cutting the frame by the shoulder usually formed on the arm is avoided, and means provided by which as one side of the arm wears it may be turned in its bearing to present a comparatively unworu surface to the action of the wheel.

The invention consists in the peculiar construction and combination of parts, as more fully hereinafter described.

In the accompanying drawings, A represents a section of sulky-plow frame formed of (No model.)

iron, the vertical parts of such frame having suitable holes formed near their lower ends of sufficient diameter to receive the arm B,which is threaded at one end where it passes through the frame, and nuts C are provided which e11- gage with the thread of the arm, one upon each side of the frameleg. The outer end of the arm is provided with linch-pin holes or other devices for securing the wheel in place upon the arm.

In practice one nut is engaged upon the arm and running near to the end of the thread, and the threaded port-ion of the arm is then passed through the frame and secured in place by the other nut. Vhenever lost motion is found or too much play in the wheel is occasioned by the wear of the parts, one of these nuts,forming an adjust-able shoulder upon the arm in connection with the other nut, forms means for taking up or adjusting such lost motion and of securing the arm rigidly in-its connection with the frame. Vhenihe lower part of the arm wears, one of the nuts may be slightl y loosened and the arm partially rotated and the nut again tightened,whcn the same result will be produced as though a new arm had been put in.

I am aware that wheel-spindles have been made removable, and that means have also been provided for adjusting such spindles in their bearings. Such features broadly,therefore, I do not seek to cover in this application. In my device the two nuts serve as jam-nuts against each other and provide very reliable securing means, while the outer of the nuts furnishes a bearing for the hub of the wheel.

\Vhat I claim as new is- The combination, with the frame A,having perforated vertical arms, and with the spindies 13, having threaded portions which pass through said perforations, of the two nuts 0 C, arranged one upon either side of each arm and acting to clamp the same between them, while the outer nut serves as a hub-bearing, as Set forth.

AUGUSTUS J. GALE.
